锁定加压接骨板治疗肱骨近端骨折

Treatment of humeral proximal fracture with locking proximal humerus plate

目的总结肱骨近端锁定加压接骨板（locking proximal humems plate，LPHP）治疗肱骨近端骨折的临床疗效。方法肱骨近端骨折45例，根据Neer分型：三部分骨折33例，四部分骨折12例。经胸大肌、三角肌入路，采用LPHP固定。用Neer肩关节功能评分标准行术后患肩功能评分。对两组疗效行统计学比较。结果38例获得平均14．7个月随访。3个月内骨折愈合35例，4个月愈合3例。按Neer肩关节功能评分标准：优20例，满意15例，优良率达92％。结论LPHP治疗肱骨近端骨折具有固定牢靠、并发症少、满意率高等优点，是一种较好的固定肱骨近端骨折的内置物。

Objective To summarize the clinical effect of open reduction and internal fixation for the proximal humeral fracture with locking proximal humerus plate（LPHP）. Methods A total of 45 cases with complex humeral fractures were operated via deltoid-pectoral approach. According to the Neer classification, there were 33 cases with three-part fractures and 12 with four-part fractures. Neer numerical rating system was employed to evaluate postoperative function of the involved shoulder. Results Of all, 38 cases were followed up for a mean 14.7 months, which showed fracture union within 3 months in 35 cases and fracture union within 4 months in 3. According to the Neer numerical rating system, result was excellent in 20 cases and satisfactory in 15, with total excellence rate of 92%. Conclusion LPHP is characterized by stable fixation, minor complication and high satisfaction, and hence is an effective method for proximal humeral fractures.
